Computer-aided pronunciation training (CAPT) technologies enable the use of automatic speech recognition to detect mispronunciations in second language (L2) learners’ speech. In order to further facilitate learning, we aim to develop a principle-based method for generating a gradation of the severity of mispronunciations. This paper presents an approach(More)
Characteristics of auditory perception plays an important role in hearing assessment. In this paper, for embedded platform, we proposed a model transforming amplitude to SPL with acoustic parameters based on auditory characteristics, achieved the automatic generation of standard pure tone test signals. We designed adjustment rules for test signals based on(More)
